Interradio issues

• Mopidy: a server-client system, complicated & instable 👎
• PyRadio: not bad, nice maintainer, but features were too difficult to add for me 👍
• Mplayer: a dead project; very instable 👎
• mpv: Python-wrapper available (libmpv-dev/python3-mpv) 👍👍

RaspberryPi issues

Input/output

• rpigpio: debouncing is crappy 👎
• rpigpio: pulse width modulation (PWM) is crappy 👎
  PWM is needed for display dimming
• now using pigpio as a system service (daemon) 👍👍

System and connection

• monitoring WiFi (radio signal strength RSS/RSSindication)
• easy & quick ways of restarting:
  • restarting the player only
  • restarting the WiFi connection (WiFi stack) only
• clean shutdown sequence (long keypress)
• minimizing memory wear: disabled syslog; own debug logging goes to → RAM

Further features

• Now take your seat, a drink and let's move to the code and Readme!
